This port receives mes-
sages from a computer-
based control system,
providing integrated
control of all preamplifier
functions. For details,
see the developer's ref-
erence: 

This remote connector
is used with third-party
remote control systems
that provide RC-5 (IR)
data via a wired con-
nection. A stereo tip,
ring, sleeve 1/8” mini
connector is used in the
following configuration: 
Tip = RC-5 data
Ring = +5 V
Sleeve = GND.

(12 V trigger)
There are 2 outputs and
one input that send and
receive 12 VDC power
on/off (trigger) signals to
and from other Krell
components, and other
devices that incorporate
a 12 V trigger. This
allows other compo-

nents to be turned
on/off, or to/from stand-
by, through the remote
control.
